HPE-compatible 32 GB DDR4 RDIMM

This registered ECC module targets administrators upgrading HPE servers or workstations that require 2666 MT/s DDR4 memory. The single 32 GB stick uses a 2Rx4 organisation and 288-pin RDIMM form factor to fit qualified platforms.

1.2 V operation with no heat spreader

Running at 1.20 V the module draws minimal power and produces little heat, so standard server airflow is sufficient for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation under sustained workloads.

Rigorous stress testing and lifetime replacement

Every unit is stress tested under load before shipping to verify compatibility with HPE part numbers 815100-X21, 815100-H21 and 815100-K21. A lifetime replacement guarantee backs the module, and experienced IT support staff are available to assist with installation questions.

Questions about this item

How do I install this 288-Pin DDR4 RDIMM in my HPE server, and what step is often missed?

Align the notch on the 288-Pin module with the slot key, press firmly until both ejector clips click shut, then verify in BIOS that the 32GB module registers at 2666 MT/s with ECC active.

What maintenance or replacement will this ECC RDIMM need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts. Replace only if system logs report uncorrectable ECC errors or the module fails POST.

What limit appears first when this 1.2V CL19 2Rx4 module runs sustained workloads?

The CAS latency of 19 cycles at 2666 MT/s sets the timing floor; sustained throughput is bounded by the PC4-21300 data rate and the registered buffer adding one cycle per command.
